I have a Audio-Taper Potentiometer that I bought from RadioShack and would like to hook it up in-line to my sub woofer so my 5.1 surround sound's bass is not so loud. However, the connections from the sub to the main receiver are proprietary plug on the back of receiver so I can't tell which is positive or negative. Does this matter for hooking up a Potentiometer? Where can I find a wiring diagram?
